通过对构造煤特征、构造应力场特征、地质构造带煤层瓦斯赋存规律和构造组合特征的综合论述,分析了地质构造物理环境对煤与瓦斯突出的影响。分析表明:构造煤分层的存在为煤与瓦斯突出的初始激发和持续发展创造了有利条件,地质构造破坏复杂程度、构造带煤层瓦斯赋存状态、构造应力场叠加和构造煤发育是影响突出发生的关键因素,增加了突出发生的危险性。提出了构造物理环境和采掘活动等扰动因素的综合作用控制地质构造带的煤与瓦斯突出。
Based on the comprehensive discussion of tectonic coal features, tectonic stress field characteristics, gas occurrence rules and tectonic assemblage features in geological structure zones, the influence of geophysical environments on coal and gas outburst is analyzed. The analysis shows that the presence of tectono-coal strata has created favorable conditions for the initial excitation and sustained development of coal and gas outburst, the complexity of geological tectonic destruction, the presence of gas in structural coal seams, the superimposition of tectonic stress fields and the development of tectonic coal are prominent The key factors that have occurred have increased the risk of salient occurrences. The combined effect of disturbance factors such as physical environment and extractive activity is proposed to control the coal and gas outburst in the geological tectonic belt.
